Huygens wave theory:
Huygen's wave theory is not correct in all respects.
2. It assumes simply that light energy is propagated as a wave.3. At the time of his proposition Huygen's did not have any idea about wavelength or about the transverse nature of light.4. So Huygens wave theory was Later modified by Thomas Young and Fresnel.5. They introduced the concept of wavelength and assumed that light waves are transverse.6. By these assumptions they could successfully explain not only the rectilinear propagation of light but also the phenomena of interference, diffraction and polarization of light.
The first question one might ask about ferromagnetic material is the source of the large magnetism. The saturation magnetization is so large virtually all the magnetic dipoles in t
How do you use operational amplifier as differentiator and adder/subtractor. Fig. shows differentiator or differentiation amplifier. As its name implies, circuit performs mathe

A) Wirte two materials that are magnetic and two that are non-magnetic? B) Explain magnetic induction C) Describe what is meant by "Magnetomotive" force?
In the case of orientation polarization we have material with built _in dipoles that are independent of each other, i.e. they can rotate liberally in sharp distinction with ionic p
why can one ignore quantization of charge when dealing with macroscopic charges
The idea that everything is made up of very small particles has been developed over many years supported by several experiments: (i) Brownian motion :
Ferromagnetic Substance: A substance which behaves as a magnet in presence of a strong magnetic field is known as ferromagnetic substance. E.g. Iron, Nickel
Faraday constant; F (M. Faraday) The electric charge carried through one mole of electrons (or singly-ionized ions). This is equivalent to the product of the Avogadro constant
